I know there have been a couple of threads on this. We did it to ours. We now have a Houser frame and are looking to sell our Lonestar/EX/yzf426 frame in a couple of weeks.

Kyle, I can help you, at a much cheaper price than eastcoast or anyone else.

Titanium pivot bolt and sleeve
Titanium motor mount bolts and aluminum spacers
Steel Motor mounts
Oil Rezzy with lines
Machined Carb intake sleeve
Gussets
Rezzy and Radiator mounts
Extended Kickstarter

$700

All you need after that is a pipe, and radiator, and a welder to weld mounts to your frame. You will also need a custom throttle cable from baldwin motorsports.

Here's my project.

Heres a eastcoastatv project, yz426 in a 400ex frame.

[forum]

eastcoast is a rip off talk to bubs. Or email adam sick. 650$ for billet mounts pipe and silencer air boot mod, directions and whatnot. email me at forum31@hotmail.com if you want his email.

Also Is there anyone out there that wants to sell a 426 engine. I need one.

dawzie please email me if you are still looking to sell that frame - i have a brand new 2000 yz426 sitting in my garage waiting for a new home. email = jalcorn@dickcorp.com

The frame is for sale - it is well used and the bottom tubes are a bit damaged, but useable. Our new Houser frame was supposed be shipped yesterday. They have not returned my calls yet. Once we get all of our stuff into yhe new frame, it will be shipped to whoever. Highest offer will get it

I dont know whats different but there is a differance. Now that I think about it, I think Walsh said the CRF is taller than the YZF. I believe he is making his frames with a removable top rail section so the valves can be adjusted.

[Hondaguy]

dawzie can you post some picks of your 426. thanks

[dawzie]

Im going to buy a dit. camera tonight

[Hondaguy]

i have some questions for you guys that already have did the convertion. do you have to modify anything on the motor. what radiator to you use. will the 400 oil container still work. were could i buy the motor mounts and what ever else i need to do the convertion. and is this going to be hard to do.

[Hondaguy]

hey mxbubs is that a 400 or 250R frame.

[Mxbubs]

Ahhhhhhhhhhh, makes you wonder dont it? Its actually a 400ex frame, I cut the angled tubing and welded some upright like on the 250r, I had to because I got a big bore radiator that is taller than the stock 250r rad. I will be done soon, and will post pics and COMPLETE directions to walk you thru it. I will post the dimensions and width of the spacers, bushings, motor mounts, oil rezzy etc., so dont know one going throwing money away to East Coast Atv or anyone else, you can do this your self.

[400exBro]

that would be great help, so i will know how much money i will need to save up to get the project done..

Well i didnt buy the Dit. camera. Once we get the frame stripped down, I'll take some pic's, scan and post, no problem. Houser said he shipped our new frame last Thursday and the swing arm this coming Tuesday. Then the only other thing I have to wait for is the Shock from Baldwin. He said this week but he has been known to put you off for weeks also.:(

[Foxrage]

Hey dawzie when you get your digital camera post some pics of that C-dale too.

Anyone know of a conversion for the CRF other than east coast atv? Thanks

I would be interested in the Machined Carb intake sleeve . My bike will be done right after christmas and this part would be nice!
